PROBLEM TO BE SOLVED: To provide a ventilating air conditioning facility capable of automatically and stably ventilating and air conditioning the inside of a building having a radiation control area of a nuclear power plant with high efficiency and at a low cost. SOLUTION: The ventilating air conditioning facility is composed of a supply air treating apparatus 4; an exhaust air treating apparatus 15; a heat exchanger 7; ducts 6, 8 supplying fresh air treated by the supply air treating apparatus 4, into the building 19 through the heat exchanger 7; a bypass duct 9 supplying the fresh air into the building 19 without going through the heat exchanger 7; ducts 11, 12 leading exhaust air from the inside of the building 19 to the exhaust air treating apparatus 15 through the heat exchanger 7; a bypass duct 13 leading the exhaust air to the exhaust air treating apparatus 15 without going through the heat exchanger 7; an automatic air quantity regulating damper 22 provided at one of the bypass ducts 9, 13; and a temperature detector 20 detecting the temperature of the fresh air supplied into the building 19. The opening of the automatic air quantity regulating damper 22 is automatically adjusted based on the detected temperature of the temperature detector 20. COPYRIGHT: (C)2009,JPO&INPIT
